INTRODUCTION
A blockchain is a ledger of transactions that are
distributed across the participating nodes in a network. It is a
decentralized database of the records of every single transaction that
has been executed, finalized and divided among the participants of the
blockchainsystem. Blockchains run on peer-to-peer (P2P) networks where
there is no central server and all the nodes (computers) in the network
are responsible for maintaining node integrity . Blockchain
technology utilizes cryptography as a means to allow each participating
node in the P2P network to update the blockchain without the need for a
central authority. Each node maintains a list of the complete blockchain
which is updated upon every completed transaction.
ABOUT HUSSY TOKEN
Employees
in typical (non-Blockchain) companies are usually paid in regular
monthly payments, e.g. 12 times per year. Vesting contracts simplifies
this process and allows team members and advisors to be paid in ERC20
tokens in as many payments as they want.
Vesting
contract allows to lock any given amount of tokens for any given
duration, while only an aliquot part of this total amount is releasable
at given time. Token vesting ensures a long-term commitment of people
working on a project with more flexibility than common employment
contract.
At HUSSY.io,
we are using the standard and reliable OpenZeppelin token vesting
contract. Source code of this contract is available in the official GitHub repository of the OpenZeppelin project.
There are two functions for interaction with the OpenZeppelin TokenVesting smart contract:
- release(ERC20Basic token) — Releases the releasableAmount of tokens to the beneficiary address. This operation can be executed by anyone.
- revoke(ERC20Basic token) — Releases the releasableAmount of tokens to the beneficiary address and the remaining unvested tokens are refunded back to the contract owner. This operation can be executed only by the TokenVesting contract owner.
What is the token vesting factory?
Factory
is a software design pattern for creating instances of a class. Using
this pattern simplifies creating new vesting contracts and saves
transaction costs (“gas”). Instead of deploying a new TokenVesting contract for each team member, we deploy a single instance of TokenVestingFactory that ensures the creation of new token vesting contracts.
